36# DESCRIPTION:
37#	Verify 'destroy -r' can correctly destroy a snapshot tree at any point.
38#
39# STRATEGY:
40# 1. Use the snapshot -r to create snapshot for top level pool
41# 2. Select a middle point of the snapshot tree, use destroy -r to destroy all
42#	snapshots beneath the point.
43# 3. Verify the destroy results.
